my choose for a perfect guest murderer would be leslie nielsen. I think that he is very goofd and would play a nasty villian like the person he played in creep show

Oh man that was a creepy skit with him burying Ted Danson in the sand.

Glub-glub-glub . . . .

This is my list, based on who would have been appropriate casting given their particular status in the 1970s.

#1-Joan Collins. Would have been far better than Vera Miles in "Lovely But Lethal."

#2-Fred MacMurray. "Columbo" would have been a great way to flex his muscles after "My Three Sons" and recall the roles he did in films like "Double Indemnity" and "The Apartment"

#3-Richard Crenna

#4-Leslie Nielsen

#5-Diana Rigg and Patrick MacNee in the same episode. (Who knows, maybe inspired alternate casting for "Dagger Of The Mind"?)

#6-Julie London. If they'd written the Faye Dunaway script in the 70s, Julie would have been ideal for that part.

Wasn't Julie London nurse McCall on Emergency???

Yes, that's her biggest TV claim to fame. Before that, she was well-known as a very sultry nightclub singer.

For obvious reasons, I've often thought of Ben Gazzara.

ahh, grant!! my heart would melt!!!
